It should be understood that the serving head Y12, capstan 13 and take-up spool 14: areV all driven from the shaft 2O through the lclutch 22, one of'which clutchesbeing'provided in each unit, whereas the distributors of each and all ofthe units are operated tof gether from the drive shaft 15. Y `,The apparatus'thus far' described does not in itself constitute a part of thepresentinvention but is being disclosed in this application forthe sake of clearly illustrating a specific embodiment of the invention.

The construction and operation ofthe takeup mechanism which constitutes the subject matter of the present invention will now be described.V As shown in Fig..2, the shaft 3() has fformed, at. its .upper end, a pinion 5,4 wliichmeshes with an internal gear formed in a circular'disk 56; VThe disk 56 is provided e with ahub portion 57 which is free to rotate formed at the upper end of the sleeve 59, a-

about a vertically disposed sleeve 59 rigidly supported in the housing 415.v Rotatably mounted within the sleeve 59 is a vertically disposed spindle60 to which is secured an in verted cup shaped 'member 62. Aj reduced portion 63 of the spindle 60 extends upwardly beyond the member 62 and is adapted to receive the take-up spool '14 which is secured to the member 62 so as tobe rotatable therewith vby means of a pin 64 fastened to the member 62 and engaging an-aperture formed in the head of thespool. kv Encirclinga raised kportion 65 formed on the under side of the member 62 is an annular friction pad 66, the bottom side of ,which` engages a circular disk 67. The disk 67 is rotatably supported upon anannular flange68 'pluralityof friction reducing ball bearings 7 O*70"being provided to cause the disk67 to rotate freely. Vinterconnecting the disk 67 and the disk 56 is arspiral spring 72, the outer endof which is fastenedto/ a pin 73 secured i to the disk 56..while its inner end is fastened toa pin 7 a secured tothe disk 67. Due to this construction, it is obvious that rotation of the disk 56 in a clockwise direction (F 3)V causes a winding" of the spring 72, since the disk 67 tends to .remain stationary due to the weight of the member 62 and,thetake-upV apparatus, which, obviously, depends upon the tensionV of the strand being reeled. Y

4Vhen operating the above .described ap` paratus, the shaft 15 yisconstantly driven, and

thus, the distributors of all of the-units are Y continuously in motion. j By operating a clutch 22, one of which is provided in each unit, the serving head, capstan and take-up spool of any particular unit may be set into'V motion. As hereinbefore described, the disk 56-rotates in a clockwise direction (Fig. 8)

yandin so doingfcau'ses ajwinding of the Y spring 72until the amoimt of tension introduced therein is sufficient to start rotation of ythe disk'67 which, in turn, drives the take-up spool 14 through thefrictional contact of the friction pad 66 with the bottom surface of the member V62 `and the upper surface of the disk 67 The constructiongof the spring 1s such that the disk 56 makes approximately one-half 'of arevolution before the 'disk y67 and take-up spool 14 start to rotate. Y This,

of course, depends v upon the tension on the strand and the weight of the spool, the latter of which varies as thespool is built up.

Y:During the operation of the apparatus, the

strand is constantly maintained under a sub-v stantially uniform tension due' to theY elasticityrof the spring 72v which serves to corn-y pensate for or take up any irregularities 1nv the tension on V'the strand being reeled, whether such irregularities be increases or decreases in the tension on the strand.y Assuming first, that during the operation of the apparatus, the tension on the strand tends to increase, it will be obvious that such tendency is overcome byy a-winding of the spring 72.v .which serves to slow down the rotation of the take-up spool, thereby preventing any increase in the tension on the strand. VAssuming now that the tension on the strand tends .to decrease, it will be obvious that suchwtendency is overcome by an unwinding ofthe spring 72 whichtends to speed up the rotation of thetake-upispool, thereby preventing any decreasefin the tension on the strand. Thus, the tension on thestrand is maintained substantially uniform throughout the operation of the apparatus.

yRefer-ring to Fig. '1, itis apparent as Vthey distributing, roller .44, .moves f downwardly from the position shown in kfull outline to the traveling path of the strand between the capstan and the take-up spool gradually decreases and that this path gradually increases when'the distributing roller moves vin the opposite direction.` Therefore, as the distributing. roller moves 'downwardly fromY the position shown inrfull outline to the .position shown in dotted outline, it is obvious Jthat a certain amount of slack is introduced in Ythat portionof the strand extending from the capstan to the take-up spool. VThis slack is taken up by an unwinding 'ofV the spring 72 which tends to rotate'the spool in a direction to wind the surplus material.. Assuming now Vposition shown in dotted `outline,.tliat the Y y thatthe distributingroller is traveling in the ropposite direction, that is, from the position shown in dottedoutline tothe position shown in full outline, it isjapparent that the tension on the strand tendsv tok increase since the traveling path ofthe strandisincreasing;

' y This tendency ris overcome by la, winding of Vthe spring 72 Which' tends to rotate the take- 5 up spool jin a direction to pay off sutlicient i material tol compensate for `the increasingy length'of the travelingpath of the material.

Itshoul'd be understood that theabove decations Within 'the scopey 'of the, appended claims.'A W V i yscribed condition Vis present Whether the capstan yis Vat restv or iii motion.' The strand is thus constantly maintained under a substantially uniformtension. y
